Abstract

The utility model relates to the technical field of medical equipment, specifically disclose a needle is exempted from in operation. Including the operation needle body, the elastic lead wire of operation needle body afterbody one side rigid coupling colludes, and operation needle body afterbody opposite side rigid coupling has the card line support that can collude with the lead wire and form the pinhole, and it has the spout to collude to open the lead wire, and it has the card line support male closed ring to slide to be equipped with in the spout, the utility model aims to solve traditional operation needle when passing the pinhole, because the pinhole of operation needle is more tiny, lead to the condition such as needle threading difficulty easily, the problem that the operation risk increases.

Description

Operation threading-free needle

Technical Field

The application relates to the technical field of medical instruments, and particularly discloses a puncture-free needle for an operation.

Background

The surgical needle, also known as medical suture needle, mainly used surgical suture, mostly stainless steel wire is drilled or grooved at the needle tail, the surface is polished and electrolyzed, it is very smooth, the needle shape is divided into according to the actual need: round needle, angle needle, shovel needle, straight needle etc. the radian can divide into as required: 1/2, 3/8, etc.

At present, a needle hole at the tail of a needle used in a hospital is small, when the needle is threaded, hung and sewn, the requirements on the eyesight and the speed of medical staff are strict, the eyesight is easy to fatigue, the situations that the needle is difficult to thread, untimely and the operation time is wasted are caused, and the operation risk is increased.

Disclosure of Invention

The utility model aims to solve the problem that the traditional operation needle is easy to cause the situations of difficult needle threading and the like and increase the operation risk because the needle hole of the operation needle is small when the operation needle passes through the needle hole.

In order to achieve the above object, the basic scheme of the utility model provides a needle is exempted from to wear in operation, including the operation needle body, elastic lead wire hook of operation needle body afterbody one side rigid coupling, operation needle body afterbody opposite side rigid coupling have can collude with the lead wire and form the card line support of pinhole, and it has the spout to collude to open the lead wire, and it has the card line support male closed ring to slide to be equipped with in the spout.

The principle and effect of this basic scheme lie in:

1. when the elastic lead hook is in a normal state, the elastic lead hook is usually propped against the wire clamping support by utilizing the elasticity of the elastic lead hook, so that when the elastic lead hook is used, the lead hook and the wire clamping support form a needle hole, and the wire can be hung conveniently.

2. When the wire is hung, a user can directly scratch in the wire from the gap between the wire hook and the wire clamping bracket to finish normal wire leading and wire hanging.

3. In order to prevent the surgical thread from sliding out from the gap between the lead hook and the thread clamping support in the normal use process of the hand needle and influence the surgical suture effect, a sliding groove is formed in the lead hook, the sealing ring is arranged in the sliding groove in a sliding mode, after the surgical thread is drawn into a needle hole formed by the lead hook and the thread clamping support, the sealing ring slides in the sliding groove, and meanwhile, the thread clamping support is inserted into the sealing ring, so that the surgical thread can be prevented from sliding out of the needle hole.

Compared with the prior art, the utility model discloses can effectively improve the efficiency of threading a needle and hang the line, save time reduces the appearance of the unexpected condition of operation.

Furthermore, the free end of the wire clamping support is fixedly connected with an ejector pin facing the lead wire hook, and the lead wire hook is provided with a functional hole into which the ejector pin can be inserted. The thimble is inserted into the functional hole, so that the use stability of the puncture-free needle in the operation is further improved.

Furthermore, a clamping groove matched with the closed ring is formed in the wire clamping support. The closed ring is clamped into the clamping groove, so that the use stability of the puncture-free needle for the operation is further improved.

Further, the depth of the clamping groove is consistent with the thickness of the closed ring. Can improve the smoothness of use.

Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present application, the drawings needed to be used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present application, and it is obvious for those skilled in the art to obtain other drawings based on these drawings without creative efforts.

FIG. 1 illustrates a front view of a surgical needle-less set forth in an embodiment of the present application;

fig. 2 shows a partial enlarged view a of the surgical needle-free proposed in the embodiment of the present application.

Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.

Reference numerals in the drawings of the specification include: the surgical needle comprises a surgical needle body 1, a lead hook 2, a sliding groove 3, a sealing ring 4, a thimble 5, a wire clamping support 6 and a clamping groove 7.

The embodiment is shown in fig. 1, the left side of the surgical needle body 1 is a needle point, the right side of the surgical needle body 1 is a needle tail, as shown in fig. 2, a lead hook 2 is welded on the left side of the tail of the surgical needle body 1, a wire clamping support 6 capable of forming a needle hole with the lead hook 2 is welded on the right side of the tail of the surgical needle body 1, another chute 3 is processed at the free end of the lead hook 2, a closed ring 4 capable of accommodating the insertion of the wire clamping support 6 is arranged in the chute 3 in a sliding mode, an ejector pin 5 facing the lead hook 2 is welded on the top of the wire clamping support 6, a functional hole capable of accommodating the insertion of the ejector pin 5 is formed in the lead hook 2, a clamping groove 7 matched with the closed ring 4 is formed in the wire clamping support 6, and the depth of the clamping groove 7 is consistent with the thickness of the closed ring 4.

When the suture guide device is used, as shown in fig. 2, the closed ring 4 firstly slides to the uppermost end of the sliding groove 3, then the closed ring can be directly drawn inwards from a gap between the lead hook 2 and the wire clamping support 6 to complete normal lead and wire hanging, and then the closed ring 4 slides to the lowermost end of the sliding groove 3 and is clamped into the clamping groove 7 in a proper manner, so that the wire hanging work of the operation is completed, and the operation suture work can be started.

The utility model discloses can effectively improve the efficiency of threading a needle and hang the line, save time reduces the appearance of the unexpected condition of operation.

Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
